When should detention basin inlets and other control structures be inspected?

The most effective time to inspect detention basin inlets and other control structures is after each major storm event. This is because significant rainfall can lead to increased runoff and the potential for sediment accumulation, blockages, or other changes in the condition of these structures. After a major storm, it’s crucial to assess whether the control measures are functioning as intended, ensuring they are clear of debris and able to manage future stormwater effectively.

Regular inspections can help identify necessary maintenance or repairs that will prevent more significant issues down the line, such as flooding or erosion. While inspections at other intervals, like monthly or annually, can also be beneficial, post-storm inspections are particularly important to ensure the effectiveness of erosion and sediment control measures directly after they may have been stressed by heavy rainfall. Inspecting only when signs of flooding occur is not proactive enough to effectively manage potential problems before they worsen.
